Abstract

The present invention relates to a method for fabricating a dental restoration, comprising the steps of rendering (S) a first digital tooth model with a first material combination for generating a first actual data set representing the optical properties of the first digital tooth model; determining (S) a first deviation between a target data set and the first actual data set; rendering (S) a second digital tooth model based on a second combination of materials to generate a second actual data set representing the optical properties of the second digital tooth model; determining (S) a second deviation between the target data set and the second actual data set; and fabricating (S) the dental restoration based on the first digital tooth model when the first deviation is less than the second deviation and fabricating the dental restoration based on the second digital tooth model when the second deviation is less than the first deviation.
